Answer to Question #67757 in General Chemistry for Rahmat

Question

(a) Briefly describe the principles involved in predicting the shapes of
simple covalent species using the valence shell electron pair repulsion
theory (VSEPR).
(b) Use VSEPR to predict the shape of each of the following species:
BF4-, PF4-, PCl4+,SF4 ; XeF4
In each case, show your working fully in order to determine the electrondomain
geometry and the molecular geometry. Sketch each molecule.
(c) Identify which of the molecules and ions listed in part (b) above, possess
a dipole moment.
